Advantages and disadvantages of high shear emulsifying machine


Release time:

2022-04-01

High shear emulsifying machine is a kind of machine that can refine the material completely evenly. Its name should come from the machine that can promote the mixing of oily substances (oil phase) and aqueous substances (water phase) to form a uniform emulsion. And there are many machines for uniform refining, such as ball mills, ball mills, pulverizers, colloid mills, dispersers, high-pressure homogenizers, etc. These machines can be used to refine materials, and their refining and homogenizing capabilities are different. The high shear emulsifying machine has the functions of refining, dispersing and homogenizing. It is mainly used for homogenization of liquid-liquid emulsification and fine dispersion of liquid-solid (powder, small particles).

High shear emulsifying machine for petroleum, chemical, daily chemical, textile, food and other industrial sectors of the decomposition, dissolution, dispersion, shear and emulsification process. The multi-functional characteristics and pure mixing principle greatly improve the mixing efficiency, and have a wide range of versatility and flexibility.

High shear emulsifying machineIn industry, when two immiscible liquids or solid-liquid inclusions are mixed, an emulsifying machine is usually used to emulsify oil and water to achieve the purpose of dispersion and homogenization. When the oil-water two-phase medium is mixed to form water-in-oil or oil-in-water, it cannot exist stably, and a suitable emulsifier is needed to improve the surface tension of the system. At the same time, the high shear emulsifying machine needs to use strong shear dispersion to break the medium into fine particles to form a stable and uniform dispersion system and achieve a good emulsifying effect. The emulsifier has a strong shearing effect, which can break the powder particles under the impact of destruction, refine to a small particle size, and then fully mix the solid particles into the liquid to form a relatively constant suspension. When the fineness of the material reaches the micron level or even the nanometer level, the system can be considered homogeneous.

The high-shear emulsifying machine can refine the material into tiny particles, link emulsification and homogenization, and obtain a stable emulsion. So the emulsifying machine can also be called homogeneous emulsifying machine. The shear head consists of a rotor and a stator that mesh with each other. Each stage of the stator and rotor has several layers of ring gears. The high-speed rotation of the rotor generates a strong centrifugal force and forms a strong negative pressure zone. The material is sucked into the working chamber and subjected to shear, centrifugal extrusion, impact tearing and turbulence in the gap between the stator and the rotor,High shear emulsifying machineThe tension of the split droplet is generated. After the liquid leaves the stator hole, the pressure rises again, causing cavitation. The homogenizing head rotates at high speed to shear, disperse and impact the material. In this way, the material will become more delicate and uniform.
